The cost to see in dollars of renting a home for the promise given by the formula c of n = 500 + 4 m where n is the number of students attending the prom calculate the cost of running the Hall of 7 0 students attend

1 answer

To calculate the cost of renting the hall for 70 students attending the prom using the formula \( c(n) = 500 + 4n \), we will substitute \( n \) with 70.

\[ c(70) = 500 + 4(70) \]

Calculating \( 4 \times 70 \):

\[ 4(70) = 280 \]

Now, substituting this back into the equation:

\[ c(70) = 500 + 280 \]

Finally, add the two values:

\[ c(70) = 780 \]

Therefore, the cost of renting the hall for 70 students is $780.
